MELVAN L. TWOMLEY, OF ANDERSON, INDIANA, ASSIGNOR TO THE SEFTON MANU-FACTURING COMPANY, OF ANDERSON, INDIANA, A CORPORATION OF INDIANA.

BROODEB.

Application filed January 22, 1912.

Z '0 all whom it may concern Be it known that I, MELVAN L. TwoMLnY, acitizen of the United States, residing at Anderson, in the county ofMadison and State of Indiana, have invented certain new and usefulImprovements in Brooders, of which the following is a specification.

My invention relates to brooders and the object thereof is to produce anovel, eiiicient and comparatively inexpensive construction of brooderfrom paper board, preferably double-faced corrugated paper board, thesame being so formed that it maybe collapsed for shipment and may bereadily erected by the user.

The advantageous features of my brooder will be apparent from thedescription hereinafter given.

In the drawings, Figure 1 is a plan view of the blank from which thebrooder proper is formed; Fig. 2 a perspective of the brooder completeset up ready for use and including the yards; Fig. 3 an elevation of oneside of the brooder proper; Fig. 4 a vertical section of the brooder;Fig. 5 a sectional plan thereof on the line 55 of Fig. 1; Fig. 6 a planview of the brooder proper in its collapsed form; Fig. 7 an edge viewthereof; Fig. 8 a sectional plan view on the line 8-8 of Fig. 10 of amodified form of construction; Fig. 9 a perspective of such modifiedform of brooder; Fig. 10 a vertical section of the brooder on the line1010 of Fig. 9; and Figs. 11 and 12 detail elevations of the brooder.

In the drawings, I have illustrated two different forms of constructionembodying my invention, one form, which is the preferred one, beingillustrated in-Figs. 1 to 7 and the other form in Figs. 8 to 12.

Referring to the particular embodiment illustrated in Figs. 1 to 7 ofthe drawings, the brooder proper comprises top and bottom portionsor-closures 1 and 2 respectively and a series of side walls, there beingin the present instance and by preference eight of such side wallsforming a brooder chamher which is substantially octagonal in horizontalcross-section. As shown and by preference, the closures and the sidewalls are formed from a single blank of suitable material' preferablydouble-faced corrugated paper board.

The side walls comprise the pairs of opposite side walls 3, 84, 4and 5,.5.the

walls 3, 3 being hinged at top and bottom to the top and bottom closuresalong suitable score lines with the exception of the outer or bottomedge of the outermost wall 3 of the blank of Fig. 1 which is hinged tothe outer or free edge of the bottom closure 2 in suitable manner as bymeans of the tape 6. The blank is slit from opposite sides part way ofits width with the result that the walls 4 and 5 while hinged to the endedges of the walls 8 are unconnected with the top and bottom and aremovable with respect thereto. These side walls are made in two sectionseach section comprising a wall 8, two similar walls 4 and two half orpartial walls 5 which are complementary and which, when broughttogether, form a single wall.

By preference and as herein shown the walls a are each provided with achick opening 4* which is so located thereon as to be in the extremeinner corners of the yard formed by the brooder proper and the yardstrips hereinafter described with the result that in the event that thechicks should huddle or crowd into such corners they will be forcedthrough the chick openings and into the brooder instead of tramplingupon each other and injuring themselves. It is obvious, however, that aless number than four of these chick openings may be used and that theposition thereof may be varied in so far as other features of myinvention are concerned.

Owing to the fact that the side walls 1.

and 5 are unconnected with the top and bottom, they may be foldedoutwardly thereby providing an opening at either or on both sides of thebrooder of the complete width thereof, thereby enabling the readyremoval of the tray 7 and the hover support and strips hereinafterdescribed. This independent movability of the walls 4 and 5 permits ofany desired amount of opening of the brooder in excess of the openingprovided by the chick opening or openings which is desirable especiallyin hot weather or for the purpose of thoroughly ventilating the brooder.

In order to hold the walls 4: and 5 in closed position as shown in Figs.2, a and 5, one or the other of the closures is provided with aprojection or projections behind which the walls, preferably the walls5, are caused to engage in detachable manner. In the present instanceand by preference, these projec tions consist of cleats 8 secured to theunder side of the top closure and near opposite sides thereof, saidcleats crossing the lines of division between the two portions or halvesof the side walls 5. By this means the walls 1 and 5 may be held inproper position but in a detachable manner so that they may be readilyopened out for the particular purposes explained and also for thepurpose of collapsing the entire brooder.

Within the brooder chamber is located a false top or hover-strip support9 having at opposite sides vertical flaps or extensions 10 which are ofsuch a height as to rest at their lower edges upon the bottom of thebrooder. This hover-strip support is of such size that it fits snuglywithin the brooder and in proper position therein without any mechanicalattachment. provision of the flaps or extensions 10 also serve tomaterially strengthen the opposite sides of the brooder and to give it amore rigid construction and at the same time permitting of the readycollapsing thereof whenever desired. From the under side of the falsetop or support depend the usual hover strips 11 and at the centralportion of such top is an opening ll provided with a screen or gauze l2permitting of the free passage or circulation of the air but excludingrodents or the like. This opening communicates with the space a betweenthe false top 19 and the real top 1 of the brooder, the circulation ofthe air being from the brood chamber below the false top, through theopening llythrough the space a and out through ventilation openings 4These latter openings are by preference formed in the upper portions ofthe side walls 41 and are provided with screens or gauzes 13. Whilethese ventilation openings 4 may be provided in any of the side wallsand may be of any desired number, yet I prefer to employ the numbershown and to locate them in the particular walls 4: as describedinasmuch as they are thereby protected or sheltered by the fourprojecting corners of the top 1.

In order to form yards at opposite sides of the brooder, I provide thetwo strips 141 and 15 which are also preferably formed of double-facedcorrugated paper board and have their opposite parallel portions 14 and15" positioned against opposite sides of the brooder along the walls 3,3 thereof and arranged to slide or telescope upon each other, the sameclosing the chick openings when fully telescoped for which purpose theyard strips are of a form complementary to the walls 4 and 5.

For the purpose of holding the yard strips in proper position relativeto opposite sides of the brooder and also to strengthen the brooder, Iprovide a rectangular band 16 enveloping the top and bottom of theMoreover, the described brooder and its side walls 3. This band ispreferably formed from a single sheet or piece of double-facedcorrugated. paper board whose free ends are brought together and hingedby means of the tape 17, Fig. 4.

In Figs. 6 and 7 I have shown the brooder proper in its collapsedcondition but it will be understood that the same may be brought withinsmaller compass for shipment purposes by folding the walls 5 on theirhinge or score lines over upon other parts with the result that theentire brooder is collapsed Within the lines of its top and bottom andgiven a rectangular form with no projecting portions liable to becomedamaged in shipment or otherwise.

Referring to the modified form of con struction illustrated in Figs. 8to 12 of the drawings the parts corresponding to those already describedare indicated by similar reference characters but primed. In thisparticular form the brooder proper .is not made from a single blank butfrom two blanks, one comprising the side walls and the top 1 and theother the bottom 2. The lower edges of the opposite side walls 3 arehingedly secured to the bottom by means of the two tapes (3. The chickopenings 5 are formed in the side walls 5, each portion being similarlyrecessed in complementary manner so that when the two portions of eachof these side walls are brought together they form a single chickopening as clearly illustrated in-the drawings. In this modified formthe false top or hover-strip support 9 has shortfiaps or flanges 9secured to the opposite walls 3 in suitable manner as by means of thestaples 9 Furthermore in this modified construction the yard strips 1 1'and 15 do not have any sliding engagement with the brooder but only witheach other, their portions 14 and 15 sliding upon each other and beingheld in any position of adjustment in any suitable manner as by means ofthe clothes pins 18; In other respects the two constructions aresubstantially the same and in particular the walls a and 5 aredetachably held in position by the cleats 8 but adapted to be readilyopened out to give any size of chick opening as illustrated in dottedlines in Fig. 8.
